摘要

Abstract

The effect of peroxide bleaching on xylan extraction, including the extracted amount from the solid res-idue, purity and whiteness was studied. The results suggested that the method with pretreatment using alkali peroxide or peracetic acid is more efficient than that of direct extraction. The best results were obtained with alkali-hydrogen peroxide pretreatment following by alkaline extraction. A final brightness of 83% , purity of 87% , and yields of 22% was obtained. Study also showed that alkali-hydrogen peroxide increased the broken points in polymers and facilitated xylan releasing. No significant difference in sugar composition was observed by FT-IR spectra detecting. Alkali hydro-gen peroxide pretreatment did not show obvious increase in the purity of product. The basic component and IR spectra from different treatment were very similar.
